MOTOGARD Series 150 Over Temperature Protection System - 120VAC - Relay Output

Motogard over-temperature protection systems provide immediate overheating protection for motors, equipment enclosures, semiconductor heatsinks, sleeve bearings, and other related machinery. Using Positive Temperature Coefficient (PTC) thermistors embedded in or in contact with the surface, the Motogard system is able to continually sense when the equipment exceeds the pre-selected temperature limits. The Motogard system changes the state of the output contacts to indicate an over-temperature condition. As the equipment cools, the switching action reverses and the output contacts change back to the "OK" condition. Thermistors must be purchased separately.
